Radiative transport equations and other macroscopic kinetic models are widely used to describe multiple scattering of wave energy in random media. They account for the incoherent wave energy, and their validity is associated with the randomness of the wave field. The opposite regime is homogenization - here, the wave field has a deterministic macroscopic limit. I will try to describe the transition from one regime to the other, and understand which one is more generic. This is a joint work with G. Bal, T. Chen and T. Komorowski.
